試題 :
1.What are the different levels of analysis in neuroscience research?
What types of question do researchers ask at each level? Please give 10
types of them.
2.Colchicine is a drug that causes microtubules to break apart (depolymerize)
What effect would this drug have on anterograde transport?
What would happen in the axon terminal?
3.When the brain is deprived of oxygen, thh mitochondria whithin neurons cease
producing ATP. WHat effect would this have on the membrane potential? Why?
4.What ions carry the early inward and late outward currents during the action
potential?
5.Define membrane potential (Vm) and sodium equilibrium potential (E Na).
Which of these, if any, changes during the course of an action potential?
6.Why is an excitatory synapse on the soma more effective in evoking action
potentials in the postsynaptic neuron than an excitatory synapse on the tip
of a dendrite?
7.List the criteria that are used to determine whether a chemical serves as a
neurotransmitter. What are the varioius experimental stratehies you could
use to show that ACh fulfills the criteria of a neurotransmitter at the
neuromuscular junction?
8.The transduction of saltiness is accomplished, in party, by a Na+ -permeable
channel. Why would a sugar permeable membrane channel be a poor mechanism
for the transduction of sweetness?
9.How does the membrane potential change in response to a spot of light in the
receptive field center of a photoreceptor? Of an On bipolar cell? Of an OFF-
center ganglion cell? Why?
10.List the chain of connections that link a cone in the retina to a blob cell
in striate cortex.
11.How do you localoze the sound in the horizontal plane and in the vertical
plane?
